Cold Saw/V1 Design Rationale/Hold System/Base

Functions

• The main function of the base is to be the part of the Cold Saw that mounts onto an external surface. The base should be elevated enough from the mounting surface such that the swivel mechanism can be adjusted from below.

The elevation can be achieved by 4 blocks, 1 under each corner of the base.

Fastening can be achieved by the use of C-clamps or fasteners after drilling holes to match the pattern on the mounting surface.

• The base also functions as a smooth surface on which swiveling parts can slide on, and provides a hole through which the swivel rod can be inserted. This hole on the base acts as the center of rotation for the swivel mechanism.

• The base is rigidly mounted to the vise such that the the rigidity of the mounting surface is transferred via the base to the vise. Rigid vise mounting is a requirement of precision operation. The fastening method is the vise 4-screwed into a flat bar that is 4-screwed into a plate. The vise must be detachable from the base such that parts of the swivel mechanism can also be isolated for modularity and ease of maintenance.

Concepts

The base involves a plate with a few holes:

• 1 Swivel Center hole

• 4 Vise Support-to-Base holes

And two blocks for elevating a flat bar on which the vise mounts:

• 2 Vise Support-to-Base holes each

And the aforementioned flat bar:

• 4 Vise Support-to-Base holes

• 4 Vise Mounting holes

And 4 blocks on which the plate rests.
